[ Upstream commit dc52aadbc1849cbe3fcf6bc54d35f6baa396e0a1 ]
Commit 21c2fe94abb2 ("RDMA/mthca: Combine special QP struct with mthca QP") introduced a new struct mthca_sqp which doesn't contain struct mthca_qp any longer. Placing a pointer of this new struct into qptable leads to crashes, because mthca_poll_one() expects a qp pointer. Fix this by putting the correct pointer into qptable.
